Google won’t just admit it’s feeding YouTube creators to its music AI

If you’ve uploaded a song to YouTube, Google almost certainly considers your video fair game for training its Lyria music AI, it just won’t admit it right now.

This is standard hedging for a legal filing: “you can’t prove we did it, and even if we did, we’re allowed to.” When asked directly if Google was using YouTube videos to train its Lyria 3 AI music model, the company declined to comment. But based on past public statements, it seems safe to assume the answer is yes.

In an interview from April 2024 with Bloomberg, YouTube CEO Neal Mohan said that “some portion” of YouTube videos may be used internally to train models like Gemini. Later that year, a blog post about creator tools confirmed as much, saying “we use content uploaded to YouTube to improve the product experience for creators and viewers across YouTube and Google, including through machine learning and AI applications.”

The company even confirmed to CNBC that it was using YouTube uploads to train Gemini and Veo. What Google hasn’t done is specifically confirm that it’s also using YouTube uploads to train Lyria.

However, in its motion to dismiss, Google says that by uploading content directly to YouTube, the plaintiffs agreed to the terms of service, which grants the company the right to “reproduce, distribute, [and] prepare derivative works,” based on the upload.

With all of that considered, it might seem odd that Google won’t just admit the obvious. But right now, the company has little to gain by going on record. And with litigation pending, maintaining plausible deniability is a calculated move.
